Method for preparing thin film nanocomposite membrane for the reverse osmosis having nano material layer and thin film nanocomposite membrane prepared thereby

摘要

The present invention relates to a method for preparing a reverse osmosis nanocomposite membrane equipped with a nanomaterial layer, and to preparing a reverse osmosis nanocomposite membrane according to the present invention, depositing a nanomaterial-containing solution on a porous support; Primary immersing the porous support on which the nanomaterial is deposited in a solution containing polyfunctional amine; And immersing the porous support on which the immersed nanomaterial is deposited in a polyfunctional acyl halide-containing solution to form a polyamide selection layer. Thus, unlike the conventional method, the solvent is free to select a solvent and between the nanomaterial and the support. Excellent adhesion, not only does not waste nanomaterials, but also has the advantage of fast deposition time.
